HAIR TRIMMER v Filed Aug. 31. 1937 JNVENTOR. ffAee/.so/v 'Lew/s BY MATTORNEY Pafenied July 1'1, 1939 UNITED STATES PATENT oFFlfcE HAIRTRIMMER Harrison Lewis, San Francisco, Calif. Applimuon-August 31, 1937,serial No. 161,777

' v,2 claims. (o1. 3o9o) The invention, Vin general, relates to bladeand comb combinations for simultaneouslylcombing and trimming hair andmore palticularly relates to a device to which practically any of thecommercial types of safety razors may readily be attached for the hairtrimming operation.

A primary object of my inventionis to provide a device of theaforementioned nature which is characterized by its ability to electsmooth and symmetrical trimming and thinning of the hair, eyebrows,burn-sides, mustache or beard and which, particularly in the trimming`of the hair, does not leave the hair in a so-calledvstep or raggedcondition.

Another important object of my inventionis to provide a compacthair'trimming device to which safety razorsof almost any type or designmay be attached in various desired angular relationships therebyaffording a Wide range of adjustability between blade and comb fortrimming the hair to any desired length.

Another object of the invention is to provide a hair trimmer of theaforementioned character which can be used effectively, rapidly andskillfully by even inexperienced persons without likelihood of injury tothe scalp or face.

A still further object of my invention is to provide an eflicient hairtrimmerr which can be constructed relatively inexpensively and which hasa minimum of parts for assembly.

Other objects of the invention together with Vmany of its advantageousfeatures willappear from the following description of .a preferred andone modified embodiment of my Ainvention illustrated in the accompanyingdrawing.

While I have shown a preferred embodiment of the invention, togetherwith a modification thereof, in the accompanying drawing, it is to beunderstood that I am not to be limited to the embodiments illustrated,as my invention, as defined in the appended claims, can be embodied in aplurality and variety of forms.

Referring to the drawing:

Figure 1 is a perspective view of a preferred embodiment of myinvention.

Figure 2 is an elevational View, partly in section,villustrating theattachment Vof a lconvex base type of safety razor to the preferredembodiment of my invention.

Figure 3 is a perspective view of a modified embodiment of theinvention.

Figure 4 is an elevational View, partly in section, illustrating theattachment of a straight back safety razor to the preferred embodimentof my invention.

In its preferred form, the hair trimmer of Vmy invention preferablycomprises a body having a substantially at bottom, an arcuate end, andan upper surface which includes a comb with relatively long, uniformlyspaced teeth merging 5 into a concave portion which, in turn, mergesinto a straight slanting portion, together with a pair of lugs integralwith the sides of the body and overlying its upper surface, said lugsbeing provided with threaded apertures for the recepl tion ofthumb-screws thus enabling safety razors of practically any design ofhead to be adjustably attached to the body for various angular lrelationships between the lcomb of the body and the blade of the razorthereby affording triml ming of the hair to any desired length.

As illustrated in Figures 1 and 2 of the drawing, I preferably provide abody II which may be molded or cast from any suitable metal, such asbrass, and which preferably includes a sub- 20 stantially at bottom I2and an arcuate or rounded end I3. 'I'he body II preferably is providedwith an upper surface which terminates at one longitudinal extremity ina comb I4 and I preferably construct thecomb portion of the 25 devicewith a plurality of relatively long, uniformly spaced teeth I6terminating in rounded points Il. The upper surface of the body IIpreferably is divided into two main portions of Y which a concaveportion I8 occupies the major 30 part of the surface. As illustrated,the`concave portion I8 merges at one longitudinal extremity with the combI4 and at its other longitudinal extremity with a straight but slantingportion I9, the latter terminating at the rounded end I3 35 of the body.Preferably, the entire upper surface of the body II, exclusive of theteeth of the comb I4, is knurled, as at 2'I, to prevent likelihood ofslippage between the head or cap of the razor and the body when the twoare as- 40 sembled.

In accordance with the invention, the body I I is provided with a pairof lugs 22 which are formed integrally with the body II and convenientlyextend from opposite sides of the body 45 ta-chment of a razor to thebody and, hen'ce,.can 55 body H of my device.

be positioned at any suitable points on the body H for effecting thisfunction.

In Figure 2 of the drawing, I have illustrated the attachment of acommon type of presently marketed safety razor to the body H, such razorincorporating a base or cap section 21 for the blade 28 which is convexon its outer surface. As shown, the convex outer surface of the base orcap 21 of the razor 26 fits snugly upon the concave portion I8 of thebody H of my device. In the position of the razor with respect to thebody H illustrated, the relationship between the comb I4 of the body andthe blade 28 is such that the teeth IB of the co-mb project anappreciable distance beyond the guard 29 of the razor and, in thisrelationship, relatively long lengths of hair may be trimmed. It isapparent that the razor 26 may be shifted with respect to the body H sothat the handle 3l of the razor assumes a differently inclined positionwith respect to the body H than that shown and in so shifting the razor,the convex surface of cap 2l may be moved forwardly toward the comb 'lllor rearwardly toward the inclined portion I9 of the upper surface ofbody H thus variably adjusting the razor to the body H for long, mediumor short trimming of the hair. This variable adjustment affords trimmingof the hair of the scalp or trimming of burn-sides, eyebrows, mustacheor beard to the desired degree and only requires a moment for theadjustment. Of course, after setting the razor in the desired positionYon the body H it requires only a turning of the thumb-screws 24 toengage the same firmly to the normally lower side of the guard 29 of therazor and thus attach the razor firmly to the body.

In Figure 4 of the drawing, I have illustrated the attachment of anothertype of conventionalV safety razor to the preferred embodiment of theinvention, such type of razor incorporating a straight back or capsection. As shown, the outer surface of the straight back of the base 2?of this type of razor is brought into engagement with the straight butslanting portion I9 of the As with a razor having a convex base andillustrated in Figure 2 of the drawing, the straight-back razor 26 maybe shifted on the slanting portion l5 of the device so .that the guard29, blade 28 and handle 3l thereof will assume differently inclinedpositions with respect to the body H. This shifting of the razor may beforwardly toward the comb i4 of the device or rearwardly toward thearcuate end I3 of the body. Moreover, if desired, the razor 26 can bepositioned on the slanting portion i9 of the device so that the leadingedge of the blade 23 will be at an angle with respect to a transverseline through the comb i4 and thereby enhance the cutting quality vforsome sections of the head. Thus, the conventional safety razor of thestraight back type, as illustrated in Figure 4 of the drawing inposition on the device, can be variously adjusted with respect to thebody H for long, medium or short trimming of the hair in the same manneras 'the convex base type of razor can be adjusted. While I have omittedshowingthe lugs 22 and thumbscrews 24 from the illustration of Figure ofthe drawing, it is to be understood that these parts function with thestraight back type of safety razor in the same manner as with the othertypes, see Figure 2 of the drawing, to hold the razor rmly attached tothe body l l in the desired position.

aieaaoi A modified embodiment of my invention is illustrated in Figure 3of the drawing. In this modification, which likewise can be molded orcast as a unit from any suitable metal, such as brass, I provide a bodyI I l having a substantially straight lower surface H2, a. straight endH3 and an upper surface provided at one longitudinal extremity with acomb H4. The comb H4 may be the same as the comb I4 of the embodimentshown in Figure 1 of the drawing and shall include a plurality ofuniformly spaced, relatively long teeth H6 terminating in rounded pointsH1. The upper surface of this modification of the invention preferablyis entirely concave in contour, the concave portion H8 extending fromthe comb l I4 to the end H3 of the body. Preferably, the juncturebetween the concave portion H8 of the upper surface and the end H3 ofthe body is rounded, as at H9. As illustrated, the concave upper surfaceH8 of body IH is knurled, as at I2l, so that the possibility of slippagebetween the body and the razor to be attached to the body will bereduced toa minimum. In this modication, I also provide a pair of lugs|22' on opposite sides of the body and these lugs may be formed integralwith the body in its manufacture. Each lug is bent inwardly, as shown,toY overlie the upper surface of the body and each lug conveniently isprovided with a threaded aperture |23 for the reception of a thumb-screwl24 which, when screwed down toward the surface H8 will engage the lowerside of the guard of a safety razor and firmly attach the razor to thebody HI. This modification is designed primarily` for use in conjunctionwith safety razors having a base or cap section for the blade with aconvex outer surface which, of course, is complementary to the concaveportion H8 of the upper surface of the body. Hence, the safety razor ofthe type mentioned can be readily and adjustably attached to the body IHfor various angular relationships between the comb H4 and the blade ofthe razor to effect long, short or medium trimming of the hair.

It is clear from the foregoing as well as the views illustrated in theaccompanying drawing that I have provided a practical, compact devicehaving a combined slanting and concave surface for affording theattachment and close fitting thereto of safety razors of various designsor types having either a fiat or convex base or cap section. Such safetyrazors may be held firmly in place upon the body or device in anydesired angular relationship so that the trimming of the hair may beeffected easily and with optimum results as regards smoothness andsymmetry and freedom from stepping or ragged ends. Moreover, that suchdevice can be rapidly used by anyone regardless of prior experience inhair trimming without likelihood of any injury whatsoever. The device isespecially useful for those i'n military or naval service Where it oftenoccurs that a fresh, neatappearancemust be had on extremely shortnotice. The attachment of the safety razor to the device of my inventionis a matter of only a few seconds and the hair, beard or burn-sidestrimming requires but a few minutes. The device has exceptional value tothose shut-in in hospitals, sanitoriums andthe like where access tobarber shops is burdensome, if Vnot impossible. In addition totheforegoing uses for individuals, it also is apparent that the device,with safety razor attached, may readily be employed to trim or thin-outthe hair of animals with safety to the animal.

Due to the fact that the device or body can be molded or cast as a unit,With the exception of the small thumb-screws, the manufacturing cost ofthe body is materially lessened. Moreover, the device has a minimum ofparts for assembly and for attaching a razor thereto, hence thepossibility of losses of necessary equipment is reduced materially.

It is to be understood that the appended claims are to be accorded arange of equivalents commensurate in scope with the advance made overthe prior art.

I claim:

1. A new article of manufacture to which a safety razor may beadjustably attached for trimming the hair to any desired length, saidarticle comprising a body, a substantially flat bottom on said body, aconcave surface on said body for cooperative adjustable engagement withthe convex surface of a safety razor base, a comb merging with andextending from one longitudinal extremity of said concave surface, aflat yto said at bottom and being adapted to be adjustably engaged by aflat surface of a safety razor base, and means on said body foradjustably attaching a razor to said body.

2. A device for use in trimming the hair and to which a conventionalsafety razor may be attached, said device consisting of a body having asurface with a concave portion and a at portion contiguous to saidconcave portion; said flat surface being inclined with respect to saidconcave portion, comb teeth on said body extending from said concaveportion of said surface, and a lug on said body having a threadedaperture therein through which a screw may be threaded to engage thebase of a safety razor and thereby enable adjustable attachment of thesafety razor to the body in any selected one of a plurality of angularor curved positions for trimming the hair short or long as desired.
